“…The most important device for the two track trigger at level-1 is the extremely fast tracker (XFT) [20]. It identifies charged particles using information from the COT and measures their transverse momenta and azimuthal angles around the beam direction.…”

“…The CDF experiment utilizes a three-level trigger system [32][33][34] to reduce the 1.7 MHz beam crossing rate to ∼200 Hz. The first two levels of the trigger system are custom hardware (the second level also has a software component) and the third consists of a farm of computers running a fast version of the offline event reconstruction algorithms.…”

This paper presents a search for standard model Higgs boson production in association with a W boson using events recorded by the CDF experiment in a dataset corresponding to an integrated luminosity of 5.6 fb −1 . The search is performed using a matrix element technique in which the signal and background hypotheses are used to create a powerful discriminator. The discriminant output distributions for signal and background are fit to the observed events using a binned likelihood approach to search for the Higgs boson signal. We find no evidence for a Higgs boson, and 95% confidence level (C.L.) upper limits are set on σ(pp → W H) × B(H → bb). The observed limits range from 3.5 to 37.6 relative to the standard model expectation for Higgs boson masses between mH = 100 GeV/c 2 and mH = 150 GeV/c 2 . The 95% C.L. expected limit is estimated from the median of an ensemble of simulated experiments and varies between 2.9 and 32.7 relative to the production rate predicted by the standard model over the Higgs boson mass range studied.

“…The online selection is made possible by two dedicated hardware systems XFT [4] and SVT [5]. These two systems, at the first ad second level of the trigger, are able to reconstruct the track parameters with high precision in about 20 µs; in particular SVT uses the silicon information and allows to recognize events with tracks coming from a displaced vertex and with helix parameters compatible with a B-hadron decay.…”

In this proceeding we report the most recent results from the CDF and DØ collaborations on the rare decays of b-mesons. The presented results show a new DØ limit for B B 0 s → µ + µ − that represent the best single measurement on this mode so far, an update of the B B 0 s → φφ with, for the first time, an angular analysis on the final state, a new measurement of the B B 0 → K 0 µ + µ − and B B + → K + µ + µ − with an interesting measurement on the forward-backward asymmetry for those channels and the first observation of the B B 0 s → φµ + µ − .
